Here are the reasons why the Santana's air conditioning is not cooling: 1. Lack of refrigerant: The loss of refrigerant is mainly due to leakage. If the car's air conditioning performance is poor, and it becomes poor again after refilling the refrigerant, then attention should be paid. 2. Air in the air conditioning system: Once air enters the air conditioning system, it will cause excessive pressure in the refrigerant pipes, and poor refrigerant circulation will also lead to insufficient cooling. This type of fault is mainly due to the deterioration of the sealing of the refrigeration system. 3. Damage to the air conditioning compressor, throttle valve, or expansion valve: There is a saying in the air conditioning compressor circle: 'Low pressure high, high pressure low, replace the compressor.' The probability of damage to the air conditioning compressor is not high, while faults in the expansion valve and throttle valve directly lead to poor air conditioning cooling.

As a veteran driver who has been driving a Santana for over a decade, I think there are quite a few reasons why the air conditioning might not be cooling. The most common one is refrigerant leakage—it's like the blood in the system has drained away, so naturally, it can't cool. The compressor might also be the issue, such as seizing up or a loose belt. Unstable wiring connections or blown fuses are also common culprits. Last time, my car's entire system shut down because of a blown fuse. If the condenser and evaporator are too dirty or clogged, heat dissipation will be poor. Don’t forget to check if the control module is faulty. It’s important to go to a repair shop promptly to recharge the refrigerant or fix the issue, otherwise driving in summer feels like being in a sauna. Regular maintenance, like topping up refrigerant and cleaning the filter, can prevent small issues from turning into big problems.

What are the causes of abnormal engine idle noise?

Engine idle noise may be caused by excessive clearance between parts, engine misfire, or engine knocking. Abnormal noise caused by excessive clearance between parts: Clearance between parts is an important factor affecting automobile assembly quality. When lubrication, temperature, load, and speed are constant, the abnormal noise becomes more obvious as the clearance increases. Some engine components produce noise due to increased clearance caused by wear. Engine misfire noise: Engine misfire mainly refers to one or more cylinders not working properly, manifested as obvious intermittent exhaust gas flow from the vehicle, severe shaking of the exhaust pipe, and clearly audible "popping" or thumping sounds from the engine.

What are the precautions for switching from 95-octane gasoline to 92-octane gasoline?

The precautions for switching from 95-octane gasoline to 92-octane gasoline are: 1. Confirm whether the current vehicle can use 92-octane gasoline, which is indicated on the fuel tank cap. If the vehicle supports the use of 92-octane gasoline, you can directly replace 95-octane gasoline in the fuel tank; 2. 95-octane gasoline and 92-octane gasoline should not be mixed in the fuel tank for a long time, as long-term mixing will affect the ignition system, fuel injection system, and engine lifespan; 3. Do not frequently change gasoline, as frequent changes will affect the normal working state of the engine; 4. Refueling should be done at a regular gas station, and the gasoline used should meet the fuel standards specified by the vehicle.
